COLLAPSIBLE BOATL Application filed March 20, 1925. Serial No. 16,907.

To ZZ 'whom z't m04/ cof/wem.'

Be it known that I, Josii MAMA CAL- DERN, Jr., a citizen of the United States, residing at Rio Grande, in the county of Humacao, Porto Rico, have invented certain new and useful Improvements in Collapsible Boats, of which the following is a speciiication.

rlhis invention relates to a collapsible or knock-down-boat, the invention being intended more particularly for embodiment in a small skiff or canoe, so that the same c an be readily transported by the user, the .invention having for an object the provision of a novel and simple type of collapsible boat.

For further comprehension of the invention, and of the objects and advantages thereof,- reference willbe had to the following description and accompanying drawing, and to the appended claims in which the various novel features ofthe invention are more particularly set forth.

Fig. 1 of the drawing is a plan view of my improved collapsible boat.

Fig. 2 is a side view thereof.

Fig. 3 is a transverse sectional view taken on the line 3-8 of Figure 1.

' Fig. 4 is a detail transverse sectional view throtigh one of the gunwales, this view being taken generally on the line 4 4 of Figure 5.

Fig. 5 is a detail side elevational view of the parts sli-own in Figure 4.

Fig. 6 is an edge view of ing the same folded. v

'i' is a longitudinal sectional vie-w of the floor of the boat, showing the said floor as folded. q

Fig. S is a detail plan view showing the construction of the gunwale of the boat.

Fig. 9 is a face view showing the collapsible car or paddle used with the boat.

Fig. 10 is a similar view to Fig. 4 but showing a modified construction.

As here embodied my improved boat coinnrises a collapsible frame consisting of the ower side members 10 and the upper side members 11. These side members are parallel throughout theirrmain lengths, the lower members 10 being spaced aparty a less distance than the top members 11. lfront and rear ends these side members converge toward one another, and connect to the opposite ends of the inclined' bow and stern posts 12 and 13. These side members are constructed as indicated in Fig. 8 of the the. seat, show- At their 'y drawing, each vcomprising a series of tubes 14 having set in one end the studs'or plugs lthat engage'removably in the. end of the adjacent tubes and are fixed therein by set screWsQ'to be presently referred; to. These top and bottom side members have sockets such as entered thereinto fromthe lower turned inward over the gunwale members 11, as clearly shown in Fig. 4 of thedraw ing. I' preferably provide also a narrow decking that extends alongl the sides ofthe boat. rlhis decking is made up or comprised of a strip 24 of like material to the sheathing 23 that is fitted over the top of the latter fas shown in Fig. 4, the two parts 23 and l24' having registering eyelets such as 26 of generally ellipticalV form, through which are passed the fastening screws 27 that hold the said parts in place', certain of tl'iesescrews being arranged to bear on the tops of the ribs 21 and act to retain the latter fixed to the members 11,A as well as secure the sheath-v ing and decking elements to the said menibers 11.

To constitute a flooring for my improved collapsible boat, I .provide a series of boards 30 that are of a length equal `to the distance between the remote sides of the lower side members 10 and which are arranged transversely Yof the boat with their ends resting on the said members 10. These boards are preferably all linked` together by means of the rings 31 that are passed through apertures 32 in the edge portions of the boards. This method of joining the flooring boards to one another permits of the same being folded one upon the other into avcompact bundle as indicated in Fig. 7 of the drawing.

The seat for my improved boatiis made up of two sections these sections comprising short boards 35 that are hinged to one another at adjacent ends, or midway between opposite ends of the seat. Hinged to the ends of the seat are hooks 36 that are caught around the gunwale members 11- and'support the seat. To prevent the two halves of the seat from collapsing on one another ion when the seat is in use a bar 37 may be pivotally connected at one end to one section of the seat as at 38 to swing parallel to the seat and engage under a cleat 39 arranged obliquely on the other section of the seat. The seat when not in use may be foldedv as indicated in F ig. 6 of the drawing. Suitable oars or paddles such as that shown in Fig.' 9 are provided, these oars or paddles each consisting of a bladeV 42 and a number of detachable handle sections 43.

In theconstruction shown in Fig. 10 of the drawing the sheathing Q3 is ,carried downward inside the gunwale as at 23 and is formed with a number of eyes such as 45 through which are passed fastening arms such as 46 turned backward to lie along the ribs and Aengaged within collars such as 48 slidable along said ribs to retain them in position. This construction enables the sheathing to be readily stretched over the frame, and the use of the set screws may be dispensed with to hold the ribs engaged with the top and bottom side members since the sheathing, when stretched, acts in this manner.

My improved collapsible boat may be readily taken apart and assembled, and when in collapsed position may be readily inserted in a bag tor transportation.

Having thusdescribed my invention what I claim as new and desire toprotect by Letters Patent of the United States is as follows l. A collapsible boat comprising a frame made up of topand bottom side members l each consisting of a number of sections detachably secured to one another, ribs extend-v ing between the upper and lower side members and detachably secured to the same, and a flexible slieathingelement detachably secured on said frame, and a flexible decking element separate from said sheathing element secured upon said frame.

2. A'collapsible boat comprising a frame made up of top and bottom side members each consistingof a number of sections detachably secured to one another, ribs extending between the upper and lower side members and detachably secured to the same, and

a flexible sheathing element detachably secured on said frame, and a iexible decking Velement separate from said sheathing element secured upon said frame, said flexible decking element overlapping the top edge of saidy sheathing element, said two elements cured on said frame, and a collapsibleflooi inglforsa-id boat, saidv iiooring being made up of a number of transversely extending boards having apertures at their edges, Vand rings passed through the said apertures to connect the said boards together.

4. A collapsible boat comprising a frame made up of top and bottom side members each consisting of a number of sections detachably secured to one another, ribs extending between the upper and lower side members and detachably secured to the. same, and a liexible sheathingv element detachably secured on said frame, and a collapsible flooring for said boat, and a seat freely suspended from the said top side members and consisting of ytwo halves hinged to one another. ,c

5. A collapsible boat comprising a frame made up of top vand bottom side members each consisting of a number of sections detachably secured to one another, ribs extending between the upper and lower side members and detachably secured to the same, and a flexible sheathing detachably secured on said frame, and means for stretching said sheathing element on said frame, comprising arms hinged to the said ribs and adapted to be passed through eyes in the edge of said sheathing element.

In testimony whereof I have aiiixed my signature.
